To reply to D. Tsakiridis: True. Too many of us don't even know how to cook from scratch, much less produce the ingredients. No need to panic though, we can adapt to what is available, (BTD and GTDers are used to adapting) and we can continue to buy local. At least in Utah we've had a good snowfall year and won't be hurting for water.

Thinking of food shortages reminds me of the first time I walked through a grocery store after it sank into my head that gluten was wrecking my health. Here I was, realizing that the foods I had relied on were no longer an option and a good 80% of what was available to buy was not available to eat. It was weird. I lived off rice cakes for a week. Now, even if I had to rely on what food I have stored, and what is produced locally, I know I can adapt to anything. I may tire of the sardines Amazon had on sale recently, but I won't panic.

Perhaps people will branch out into more variety in their diets. Perhaps they will come here to find out how to cook quinoa or amaranth... Is a corn shortage next? Adapt, don't panic.
